Hi Brian,

Thanks for your reply. Unfortunately, now I'm left in a somewhat 
confused state. It's possible that I overlooked some important update item,
but normally when updating programs continue to work, and if a reconfiguration
is necessary then that's clearly shown in, e.g., the changelog.

If I correctly understand your (above) advice then you ask me to read a
document of some 20 sections, explaining the concept of
'CUPSDriverlessPrinting'. It's a thorough document, but maybe a bit over the
top for users who would merely like to be able to continue printing? 

I've now downgraded hplip to the stable version, and all's working again. But
I think an upgrade to the version in 'testing' is preferable, since my
computer's normal distribution is 'testing'. Is there maybe some quick
(step-by-step) upgrading guide explaining how to upgrade from the
stable-release software to the testing-release software without encountering
print-failures? I think such a guide would be really useful.

Please advise,
